Title: Photographic camera and method
IPC: G03B17/52
Filed: 1963-03-08
Abstract: 1,037,343. Photographic silver salt diffusion process and apparatus. INTERNATIONAL POLAROID CORPORATION. March 8, 1963 [March 26, 1962 (2)], No. 9365/63. Headings G2A and G2C. In a photographic silver salt diffusion process, prints having lateral image-free borders are obtained by exposing the light-sensitive sheet so that a latent image is formed which extends to the lateral edges thereof and employing an imagereceiving sheet which is wider than the lightsensitive sheet by twice the width of the derived border, the sheets being positioned centrally with respect to each other during transfer, and processing liquid being prevented from spreading beyond the lateral edges of the light-sensitive sheet. Apparatus for effecting such a transfer comprises transfer rollers between which the sheets are guided into superposition, the width of one roller being equal to the width of the lightsensitive sheet, and a liquid dispenser for introducing processing liquid between the sheets immediately prior to their being pressed together between the rollers, the dispenser having an elongated mouth equal in length to the width of the narrower Sheet and having flanges at each end thereof to guide the light-sensitive sheet and to prevent spreading of the processing liquid. In Fig. 1, the apparatus forms part of a camera wherein the image-recording sheet 32 is narrower than the receiving sheet 40. After exposure of sheet 32, it is pressed into contact with sheet 40 by rollers 42, 44, and liquid is spread between the sheets from dispenser 48. The roller 44 and mouth of the dispenser 48 are equal in length to the width of shut 32. The dispenser comprises a channel 54 (Fig.2) which is connected to a reservoir 66 (which is the core of the spool for sheet 40) by a pipe 72 and discharges liquid under pressure through the lips 56, which are in contact with both sheets 32, 40 as they come together between the rollers. The lips are provided with flanges 62 which serve to guide the sheet 32 and prevent lateral spread of the liquid beyond the edges of that sheet. The lips of the dispenser may be sealed by moving the rollers 42, 44 towards the dispenser. Transverse borders to the prints may be obtained by supplementary exposure as desribed and claimed in Specification 1,037, 342, e.g. as shown at 38 in Fig.1.

Title: Improvements in or relating to the treatment of carbonised metal
IPC: H01J19/00
Filed: 1938-03-28
Abstract: 512,996. Purifying carbon. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 28, 1938, No. 9438. Convention date, March 27, 1937. [Class 90] [Also in Group XL] A method of treating metal, e.g., nickel coated with carbon, for the removal of impurities which would impair its use in the formation of electrodes for electron discharge devices consists in subjecting the carbon coated metal to the action of steam at a temperature of about 350‹C., for about 90 minutes. After treatment the metal is cooled to a temperature of about 100‹C. in an atmosphere of steam before exposing it to the air. Apparatus for carrying out the method consists of a furnace 1, Fig. 2, in the form of a cylinder heated by a resistance element 8 and provided at the ends with chambers A, B, for the admission and exhaust of steam. These chambers comprise solid discs 7, 7<1> and perforated discs 5, 5<1> held in spaced relation by rods 6, 6<1>, and having a sliding fit inside the cylinder 1. The space between the ends is packed with containers 4, Fig. 3, with the carbon coated articles. Preferably, the furnace is made in two coaxial sections, the second section 9 operating at the cooling temperature so as to allow one batch of material to be cooled while another batch is being treated. Semi-cylindrical ways 13, 14 at the ends of the furnace are provided to facilitate the loading and discharge. Fig. 5, shows an arrangement for dealing with metal strip 15, in which 16 is the carbon coating device and 19 the steam treating apparatus.

Title: Improvements in or relating to electromagnetic devices having variable reluctance
Inventor: MILLER GABRIEL LORIMER
IPC: H03F9/00
Filed: 1955-04-01
Abstract: 803,235. Inductions; automatic current control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 29, 1956 [April 1, 1955; Oct. 6, 1955], Nos. 9505/55 and 28544/55. Classes 38 (2) and 38 (4). [Also in Group XXXIX] A magnetic amplifier or switching transformer comprises an annular magnetic core 2 which may be of ferrite, saturable by current induced in a winding 1 lying along the centre of the annulus, the core carrying windings such as 3, 4, 5. This current may be induced by H.F. current in winding 7 derived from an oscillator 8, Fig. 4. With D.C. in winding 3, current at double the frequency of that in winding 1 is induced in winding 4 and when it is rectified at 13 and smoothed by elements 14, 15, 16 the D.C. output at terminals 17, 18 is proportional to the D.C. input in winding 3. A tuned amplifier in the output of coil 4, results in a high-gain magnetic modulator without zero drift, Fig. 5 (not shown). To obtain discrimination between input currents of opposite sign in coil 3, the output is taken from a phase-conscious detector fed both from the tuned amplifier and from a voltage doubler supplied from the oscillator, Fig. 6 (not shown). Fig. 8 shows this arrangement in which the output is then amplified at 28, and fed back to a current source or regulator to control current to load 30 which current passes through winding 5 on core 2 and is thereby compared with a reference current in coil 3. To provide phase discrimination without using the phase conscious detector, a unidirectional saturating field may be provided. Where a high impedance input to coil 3 is required, the input terminals may be connected to the grids of two triodes, the coil 3 being connected to tappings on resistors between grid and cathode, Fig. 7 (not shown). The reference D.C. in coil 3 may be replaced by a permanent magnet, Fig. 9 (not shown). To use the device as a switch, the current in winding 1 is started or stopped to break or make inductive connection between coils 3 and 4. So that the connection may be made upon energizing winding 1, coil 3 is connected in a bridge circuit comprising inductor 33 and resistors 34, 35. A switching pulse in coil 7 inducing current in winding 1 produces unbalance in the bridge so that an output signal appears across terminals 38, 39. In alternative forms of the device, the core may comprise superimposed rings or stranded wire of magnetic alloy (Fig. 1, not shown).

Filed: 1960-03-17
Abstract: 951,614. Heat exchangers. SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. March 17, 1960 [March 21, 1959], No. 9507/60. Heading F4S. [Also in Division G6] To raise the efficiency of a nuclear reactor cooling fluid, solid particles are added to the fluid, urged along circuital paths which engage the exchange surfaces so as to raise the particle concentration at the surfaces. The particles may also act as a moderator. As shown, the surface of rod 1 is cooled by fluid flowing longitudinally along the annular passages 2, 3. A flow also occurs through slots 4, 5, 6 from 3 into 2 and the circulation paths indicated at 9, 10, 11, 12, 13, 14 is produced. Solid particles introduced into the cooling fluid collect in the outer zones of the circulation paths where they raise the heat transfer rod and the particles move helicoidally along the rod. In further embodiments, the methods of introducing and removing the particles from the fluid are described together with alternative methods of forming the circulating paths by outwardly directed jets. Specification 951,613 is referred to.

Title: Improvements in or relating to colliery "overwind" gear
IPC: B66B5/08
Filed: 1933-03-30
Abstract: 415,190. Winding - - apparatus. HEWITT, H., Hill Side, Tunnel Road, Ansley, Nuneaton, March 30, 1933, No. 9553. [Class 78 (v).] Means, in a colliery winding gear, for applying the brakes and stopping the engine if the latter is started to drive in the wrong direction, includes a cam 1 which is so driven by the engine that it makes less than a complete revolution during the complete travel of the cage. A rod 2 co-operative with the cam is connected, by links 5, 8, 9, 10, to a rock shaft 7 which is urged by a weighted arm 11 to turn in a direction effective to apply the brakes and shut off the steam from the engine. Such turning is prevented by an arm 12 pivoted to a spring-pressed slide 14 to which is pivoted also an arm 17 adapted to be projected into the path of movement of a lug 20 on the winding drum 19. During normal operation of the winding gear, the arm 17 is held to the right by the spring 18. If, when the cage is at one end of its travel, the engine is started to drive in the wrong direction, the projection shown on the cam 1 moves the rod 2 to the left, thereby rocking the shaft 7 to force the arm 17 to the left. As the drum 19 rotates, its lug 20 tilts the arms 17, 12 about the pivot 13, thereby freeing the rock shaft 7 so that it is turned by the arm 11 to apply the brakes and shut off the steam. The cam 1 may be adjustable.

IPC: C10K1/12
Filed: 1925-04-14
Abstract: 255,141. Jackson, W. J., Mellersh-, (Koppers Co.). April 14, 1925. Materials and compositions for purifying.-Fuel gases are purified from hydrogen sulphide &c. by washing them first with a suspension of a metallic compound in a liquid of relatively low alkalinity and then in a similar suspension of higher alkinity. The liquid in the first case is preferably a 1 per cent solution of sodium carbonate containing in suspension about 1 per cent of pulverized hydrated ferric oxide, while the second liquid contains 3 per cent sodium carbonate. The apparatus comprises two absorbers A<1>, A<2> connected with four aerators T<1> - - T<4> and two sumps W<1>, W<2> by valved pipes so that the flow of the gases through the absorbers may be reversed, and the absorbers supplied with either a solution of low alkalinity from the aerators T<1>, T<2> or with a solution of higher alkalinity from the aerators T<3>, T<4>. In a modification, while the alkalinity of the solution is maintained in the washing stages, the spent liquid entering the revivification stage is maintained in a neutral or slightly acid condition by the addition of acidic iron compounds, e.g. ferric sulphate or chloride acids, acid salts or sulphur dioxide. The solution may he heated to 85‹ F. as described in Specification 255,140, and the absorber used may be that described in Specification 255,142; and the aerator may comprise a tubular fabric suspended with freedom of movement as described in Specification 255,139. Free sulphur accumulating in the compartments T<1> - - T<4> may be removed by cutting out one of the compartments and passing the sulphur after settling to a centrifuge C or a filter, the sulphur then being separated from the iron compounds which are returned to the system. Alternatively the sulphur may be removed with the suspension, fresh suspension being supplied to the compartments which are kept working continuously. The sulphur may also be removed from the alkaline solution by flotation, anti-foaming agents such as kerosene being added. The ferric oxide is preferably prepared by pulverizing bog ore. Specifications 190,116 and 238,172 are also referred to.

Abstract: 1373873 Preparation of ammonia and sulphur dioxide CHEMIEBAU DR A ZIEREN GmbH & CO KG 2 March 1972 [3 March 1971] 9752/72 Heading C1A Ammonia and sulphur dioxide are prepared by heating ammonium sulphate to 300-500 C. to form ammonia and ammonium bisulphate and then burning the ammonium bisulphate at a temperature of from 850-1250 C. with a carbon containing fuel in a combustion chamber, such that an oxygen concentration of from 1 to 8% by volume is found in the gas which issues from the combustion chamber. Solid ammonium sulphate is fed in by a line 2 and mixed in a mixer 1 with an ammonium hydrogen sulphate melt. The added ammonium sulphate partially decomposes so that ammonia escapes through line 3 and the ammonium sulphate/ammonium hydrogen sulphate melt is pumped from mixer 1 through line 4 to a column 5 where it is treated in countercurrent with superheated steam. Ammonia containing steam leaves column 5 by line 6 and is purified with the ammonia from mixer 1. The ammonium hydrogen sulphate melt from column 5 is partly pumped back through line 7 to mixer 1. Part of the ammonium hydrogen sulphate melt is burnt in combustion oven 8 with a sulphur-containing fuel oil charged at 9 and the resultant sulphur dioxide containing gas is available for oxidation to sulphuric acid by the contact method, after passing the waste heat boiler 10. Superheated steam from the waste heat boiler 10 is in part fed by way of line 11 to column 5 as entrainer and is in part available at 12 for other purposes.

Filed: 1941-06-18
Abstract: 578,333. Fuze - setting apparatus. MOLINS, D. W., HARVEY, V. P., MASON, J. A., POWELL, G. F. W., and MOLINS MACHINE CO., Ltd. June 18, 1941, No. 9801 /42. Divided out of 578,330. [Class 9 (i)] A fuze-setting device, especially for antiaircraft projectiles, wherein the setting is controlled by an adjustable stop, the position of which is regulated in accordance with the predictor indication by a follow-the-pointer hand wheel and gearing, as described in Specification 578,330, comprises also means for correcting the setting, while the fuze-ring gripping device is still engaged with the ring, for the " dead-time," i.e. the time required to load and fire the gun after completion of the fuze setting; automatic means are also provided for restoring the corrector to its original position at the end of each setting operation. The worm-wheel 42, Fig. 2, on which the adjustable stop is mounted, is driven by a worm 63 on a divided shaft 64, 164, Fig. 4, the latter portion of which is rotated by the follow-thepointer hand wheel. Between the two parts of the shaft is disposed a differential gear comprising two sun-wheels 100, 101, and planet-wheels 102 carried by a carrier 105 which is rotatably mounted on the boss of the driven wheel 100. The planet-carrier is geared to a pinion 120 on the boss of the sun-wheel 101 through gears 104, 103, clutch 107 and gears 117, 118. The clutch is operated by a bellcrank 110, the lower arm of which, by a roller 109, engages a cam 108 on the main-shaft 9 of the fuze-setter. When the shaft 9 is rotated to set the fuze, the cam closes the clutch so that rotation of the shaft-element 164 to follow the predictor indications effects a consequential displacement of the planet-carrier 105. The time during which such displacement occurs is constant, but the extent of the displacement in that time depends upon the rate of rotation of the shaft 164, and hence a correction is interposed in the drive of the worm-wheel 42 which is proportional to the rate of change of the predictor indications; and by suitably fixing the gear ratios, the correction may be assimilated to the target movement during the approximately constant " dead time." To restore the planet-carrier to its original position at the end of a setting operation, two rollers 130 on the cam-drum 19 on the shaft 9 by which the fuze-gripper 1 is rotated, engage as the operation is completed with the inner end of a radial bar 129 on a pinion 123, in gear with a pinion 122 on the boss of the planet-carrier, and by returning the bar to its original alignment, bring the carrier back to starting position.
